Struct Signature

pub struct Signature(CoseSign1);

A signature cryptographically attests to a (namespace, data) pair. The namespace is included in the signature object, the data is not. One data object can be signed multiple times, with different namespaces / by different signers, depending on the application needs.

Tuple Fields

0: CoseSign1

Implementations

impl Signature

fn inner(&self) -> &CoseSign1

fn namespace(&self) -> Result<SigningNamespace, CryptoError>

pub fn content_type(&self) -> Result<CoapContentFormat, CryptoError>

Parses the signature headers and returns the content type of the signed data. The content type indicates how the serialized message that was signed was encoded.

pub fn verify( &self, serialized_message_bytes: &[u8], verifying_key: &VerifyingKey, namespace: &SigningNamespace, ) -> bool

Verifies the signature of the given serialized message bytes, created by SigningKey::sign_detached, for the given namespace. The namespace must match the one used to create the signature.

The first anticipated consumer will be signed org memberships / emergency access: https://bitwarden.atlassian.net/browse/PM-17458

Trait Implementations

impl CoseSerializable for Signature

fn from_cose(bytes: &[u8]) -> Result<Self, EncodingError>

Deserializes a serialized COSE object to a struct

fn to_cose(&self) -> Vec<u8>

Serializes the struct to COSE serialization

impl From<CoseSign1> for Signature

fn from(cose_sign1: CoseSign1) -> Self

Converts to this type from the input type.
